Spokeswoman Andrea Saul did announce that Romney raised $11.5 million in February, the second-best fund-raising month for his campaign.

Romney’s senior aides argued that Romney holds a commanding lead in the state-by-state delegate math, which required superior organizing skills that will become even more important as the campaign splays across a larger battleground.

The senior aides here delivered a clinical state-by-state dissertation on the impossibility of either Santorum or Gingrich reaching the 1,144-delegate threshold to win the nomination.

While Romney, they said, needs to win only 48 percent of remaining delegates, Santorum would have to carry 65 percent of what’s left and Gingrich 70 percent.

“The nomination is an impossibility for Rick Santorum or Newt Gingrich,” one senior campaign aide said. “All we have to do is keep doing what we’re doing [and] we can get the nomination. These guys, it’s going to take some sort of…act of God to get to where they need to be on the nomination prize.”

Romney aides went on to describe Tuesday as a “damn good night for us,” portraying their candidate’s relative strength in Ohio’s more Democratic urban areas and weakness in the rural and Appalachian counties as a benefit to his general election chances. Romney also won five of the 10 contests last night — Virgina, Vermont, Idaho, Massachusetts and Alaska.

“The areas we didn’t do as well in are rural and they are more anti-Obama,” a senior campaign aide said. “We feel very confident about how we’re going to do in those counties. And in fact we did best in those counties we’re going to have to score best in order to win the [general] election in Ohio,” the aide added, referring to areas around the cities of Columbus and Cincinnati.

Running strong in Hamilton County around Cincinnati is good for the campaign because the city “is trending more Democrat. And the fact that we did well there bodes really well for the campaign. We did well in exactly the counties we’re going to need to do well in in the fall,” the aide said.

The campaign also made the case that Santorum will lose delegates as caucus states go to their party conventions because his campaign is not sufficiently organized to follow through with securing delegates.

“You’ll definitely see, for instance, Rick Santorum taking a hit on his delegate numbers,” a senior campaign aide said. “As you guys are all well aware, these so-called delegate numbers coming out of certain caucuses are just projections, they’re not real, they’re just fictional at this point.”

“It takes a few more steps in the process all the way up until a state convention until we actually know how many delegates have been assigned and I think you’ll see at the end of the day when we re-examine these delegates that someone like Rick Santorum has lost delegates just because he hasn’t followed through on the process and candidates like Mitt Romney and the Paul campaign have.”

But the map isn’t entirely working in Romney’s favor. The campaign now turns to the Plains states and the South, not territory favorable to the former Massachusetts governor.

On Tuesday night, Santorum spokesman Hogan Gidley, a veteran of South Carolina politics, predicted that Romney will have a “real problem in the South,” and can’t win Southern states.

“I’m from the South, so I’ve got some knowledge here. Romney is going to have a tough time in the South. We think we’re going to do really well in Texas, obviously in Mississippi and Alabama. We’ll be hitting those states over the next couple of days,” Gidley said. “There are still 28 states left to go.”

Kansas, Mississippi and Alabama are the states next to hold contests — Kansas holds its caucuses this Saturday, while Mississippi and Alabama hold their contests on Tuesday.

Southern states tend to favor socially conservative candidates like Santorum, proven by the fact that the former Pennsylvania senator won Oklahoma and Tennessee on Super Tuesday. And Gingrich also holds some appeal there, though he only won his former home state of Georgia last night.

But Gingrich on Wednesday morning was unfazed by his losses.

“We are staying in this race because I believe it’s going to be impossible for a moderate to win a general election,” he said in Alabama.

The former House speaker cancelled events in Kansas and moved to refocus on Mississippi and Alabama. Spokesman R.C. Hammond said it was important for Gingrich to succeed in those states in order to remain in the contest.

“Everything between…Spartanburg [S.C.] all the way to Texas, they all need to go for Gingrich,” Hammond said.

But the Romney team argued that second-place finishes throughout the rest of the nominating process will be enough to clinch the GOP nod.

“There are no more opportunities on this calendar for big delegate pick-ups,” a senior aide said. “There are some states down the road that are big states, like California and like Texas, but none of them offer statewide winner-take-all results for any candidate.”

“So sure, there are other candidates that are going to win some more races, but we’re going to be consistently coming in second place and getting delegates in a lot of these states. Take for example, Georgia and Oklahoma and Tennessee last night. We were able to go in and win congressional district delegates in all of these places, and I think that you’ll see that continue as we go down the calendar.”

The aide argued that neither Santorum nor Gingrich would be able to compensate for a “huge deficit” in delegates by winning a future state with a “giant delegate pick-up.”
